No. 9).

[0004]

For example, consider the case where the KEY tray is disposed on the upper side and the CD tray is disposed on the lower side. When the CD tray is ejected with the KEY tray ejected, it becomes impossible to attach / detach the CD to / from the CD tray. Further, when the KEY tray is ejected with the CD tray ejected, if the CD is not properly mounted on the CD tray, the CD may be damaged.

Therefore, in the present invention, for example, the aforementioned C
An object is to prevent the D tray and the KEY tray from being simultaneously discharged.

[0006]

According to the present invention, first and second movable bodies having an operation body or a storage body are provided.
When both the and the second movable body are discharged from the housing,
In an electronic device in which first and second movable bodies are arranged adjacent to each other so that one of them obstructs the operation or storage of the other,
A control means for preventing a state where both the first and second movable bodies are simultaneously ejected from the housing is provided.

[0007]

With the above arrangement, it is possible to prevent the first and second movable bodies from being simultaneously discharged. For example, when performing an operation of ejecting the other movable body while one movable body is being ejected, one movable body is accommodated and the other movable body is automatically ejected. Thus, it is possible to prevent one movable body from interfering with the operation or storage of the other movable body, or from damaging the stored matter.
